alright.. I just needa little help or advice here 
.. maybe alot, who knows hehe..
okay, Im 15, ive had sex about 20 times... Im not really happy with how long I go though... Its just when I put my penis in my girlfriend's vagina, the feeling is... incredible. (DUH)
lol, well i watch porn ever so often and i wonder how these guys go for like an hour... it freaks me out lol.
So what im wondering is this, How can i go longer.. I usually go for about 5-10 minutes.. other times after I do it once or twice, i'll go for 30 minutes-45 minutes.. I jus twant to be able to go longer all the time so my girlfriend gets more pleasure for a longer period of time, thats all

i was trying to find that one topic on the same subject.
where a guy compared his performance to porn.
ok, first off, like wally said, don't compare you sex life to porn.
how do you know they didn't edit and take 3 takes of a certain sex session to make it look like he's been pounding her for 2 hrs...i mean really?
secondly, 30 minutes is definetly more than some guys can do and more than I can take sometimes. If a guy was pounding at me for over an hour I would start to hurt and/or be bored lol.
is your g/f not orgasming in the time it take you too??
if not do more foreplay and get her worked up. or thrust and if you feel you are getting close, pull out, and finger her or do oral to keep her going, then jump back in when you are ready.
also, you could use desensitizing creams or condoms that have "lasting pleasure". just don't put them on inside out LOL.
(episode of curb your enthusiasm) LMAO.
like I said, you don't really have anything to worry about.
here is some other posts I found.

First of all, get rid of the notion that longer is better. A long, slow session usually refers to foreplay; not actual screwing.
Good sex is about intensity, not clocks.
Porn is not the place to study technique. If you poke around this board a little, you'll discover that most guys tend to be in the 5-10 minute range (when we're talking about actual penetration and thrustring).
Explore the myriad of ways to give your girl pleasure... save the penetration for the "coup de grace."
